Wrist restraining glove

Abstract: A wrist restraining glove(110) comprises a hand receiving portion(111) for receiving a hand(H), a wrist band(113) integrally joined to the hand receiving portion(111), and a tension member(115) integrally joined on the palmar surface of at least the hand receiving portion(111). When the glove is worn on the hand, the wrist band(113) is wrapped around a wrist. The tension member(115) exerts a tensile force when pulled longitudinally, thereby an outward pivotal movement of the hand about the wrist can be suppressed.

Description: BACKGROUND OF THE INVENTION FIELD OF THE INVENTION The present invention relates to a wrist restraining glove which is suitable for golfing and by which an unnecessary pivotal movement of the wrist can be suppressed to enable an accurate and powerful swing of a golf club. The present invention also relates to a wrist restraining glove which is also suitable for sports such as baseball, tennis and by which an unnecessary pivotal movement of the wrist can be suppressed to reduce arm fatigue. The present invention further relates to a wrist restraining glove which is suitable for driving and physical working to reduce arm fatigue. RELATED PRIOR ARTS It is well-known that pivotal movement of the hand about the wrist during a swing of a golf club greatly influences the direction and speed of a ball hit by the club. For example as shown in Fig.37A-37B, during a swing of a golf club 1, the pivotal movement of a hand 50 about a wrist 53 within a plane parallel to the back 51 of the hand 50 (the pivotal movement as shown by an arrow "X" in Fig.37A, which is called as "a cocking pivotal movement" in a golf swing) is effective for making a powerful swing to increase the speed of a ball hit by a club without varying the direction of flight of the ball. However, the pivotal movement of the hand 50 about the wrist 53 to the direction perpendicular to the back 51 of the hand 50 (the pivotal movement as shown by an arrow "Y" in Fig.37B) is undesirable because it results in a decreased speed of the ball and incorrect direction of flight. US Patent No 2154197 discloses a wrist restraining glove that has a hand receiving portion and a cuff or wristlet integrally joined thereto, in which a number of pockets are provided extending lengthwise across the wrist partly on the side and partly on the back or front of the glove, and these pockets contain resilient stays which are not rigidly attached to the glove but are held by the pockets across the wrist joint to oppose movement in certain directions. US Patent No 3606343 is another attempt at improving a golf swing in which a wristlet of elastic or cloth is connected by a cord to finger loops. In the approach taken by the present invention, in particular, it is desirable during a swing of a golf club to permit or induce the pivotal movement of the hand 50 about the wrist within the plane parallel to the back 51 of the hand 50, but it is desirable to suppress the pivotal movement of the hand 50 about the wrist 53 in a direction perpendicular to the back 51 of the hand 50 (movement in an outer direction perpendicular to the back 51). However, it is quite natural for a human hand to be moved in an outer direction perpendicular to the back of the hand about the wrist (i.e. to move toward the direction "Y" as shown in Fig.37B). It is rather unnatural to move the hand within the plane parallel to the back of the hand (i.e. to move toward the direction "X" as shown in Fig.37A). Accordingly, for an amateur or untrained golf player, the hand tends to be moved outward during a swing of a golf club resulting in a decreased speed and in an incorrect direction of flight of the ball hit by the club. A similar tendency in hand movement occurs not only in golfing but in other sports such as baseball and tennis. It is considered that the speed and direction of the ball can be greatly improved if the outward pivotal movement of the hand (the outward pivotal movement "Y" as shown in Fig.37B) is suppressed without suppressing the pivotal movement of the hand within the plane parallel to the back of the hand (the sideward pivotal movement "X" as shown in Fig.37A). Further, it is also considered that fatigue of the wrist and the hand can be decreased if the outward pivotal movement of the hand is suppressed in driving (operating of a steering wheel) and in physical works (such as digging earth by a shovel). SUMMARY OF THE INVENTION It is an object of the invention to provide a wrist restraining glove which is suitable for golfing and by which an unnecessary pivotal movement of the wrist can be suppressed to enable an accurate and powerful swing of a golf club. It is another object of the invention to provide a wrist restraining glove which is suitable for the other sports such as baseball, tennis,etc. and by which an unnecessary pivotal movement of the wrist can be suppressed to reduce arm fatigue. It is a further object of the invention to provide a wrist restraining glove which is suitable for driving and physical work and are effective in reducing arm fatigue. A wrist restraining glove for restraining pivotal movement of the hand about the wrist according to the present invention comprises a hand receiving portion and a wristlet integrally joined to said hand receiving portion and is characterised by a tension member integrally joined with a palmar portion of the hand receiving portion and with the wristlet so as to be placed in tension by and to exert a tensile force against outward pivotal movement of the hand about the wrist. The hand receiving portion may comprise a finger or palm receiving ring. The tension means may be resilient. The wristlet may include an elastic portion. The tension means extends along the palmar side of the glove. The tension means comprises complementary, elongate fastening members which extend side by side in longitudinally spaced apart relation laterally across the palmar side of the hand receiving portion adjacent the wristlet and which can be brought together for releasable engagement to shorten the palmar side, thereby to oppose the outward pivotal movement of the hand about the wrist and to permit said outward pivotal movement when released. The fastening members may comprise a zip type fastener or a hook and loop type fabric fastener. The back surface of the hand receiving portion can be inclined inward from the back surface of the wristlet so that the palmar surface portion of the glove constitutes the tension means. A cut out can be formed in the palmar surface of the hand receiving portion between the complementary fastening members which close the cut out when they are brought together into engagement. The tension means may be formed by reducing the length of the palmar surface of the hand receiving portion by forming a cut out to extend laterally thereacross adjacent the wristlet and closing the opposed laterally extending edges of the cut out together, preferably by sewing. At least a palmar portion of the hand receiving portion of the glove may be made from a resilient textile material. The palmar surface portion of the hand receiving portion may be reduced in length by forming a cut out to extend laterally thereacross adjacent the wristlet and securing the opposed laterally extending edges of the cut out together by an elastic member thereby to provide an inward biassing force opposing the outward pivotal movement of the hand about the wrist. An opening can be formed on a back side of the glove and extends longitudinally from the entry end through the wristlet and along the hand receiving portion to a location adjacent the fingers, a flap form closure member and a wrist band member are attached to locations of the hand receiving portion and the wristlet, respectively, adjacent a common longitudinal edge of the opening, and complementary releasable fastening means are provided on the flap member and the back side of the hand receiving portion and on the wrist band member and the back side of the wristlet, respectively, the tension means comprising an elastic member provided on the palmar side of the glove member. An opening can be formed on a back side of the glove and extends longitudinally from the entry end through the wristlet and along the hand receiving portion to a location adjacent the fingers, a flap form closure member is attached to a location of the hand receiving portion and the wristlet adjacent a longitudinal edge of the opening, and complementary releasable fastening means are provided on the flap member and the back sides of the hand receiving portion and wristlet, respectively, the flap member providing a pocket receiving a resilient restraining plate and the tension means comprising an resilient member provided on the palmar side of the hand receiving portion, the resilient restraining plate and the resilient member together restraining the hand from outward pivotal movement about the wrist. The resilient restraining plate may have a central portion of reduced width in the lateral direction to increase lateral flexibility thereof. The resilient restraining plate may be integral with the flap member and the central portion of the restraining plate may be of increased thickness thereby to decrease flexibility in the outward direction. The tension means may comprise a resilient restraining plate and the wristlet comprise wrist band members for wrapping firmly around the wrist and having free ends with respective complemetary fastening means. The tension means is integral with the palmar surface of the wristlet and the wristlet may comprise a band member curved inwardly towards a knuckle side at a palmar side so that the palmar side of the hand receiving portion is pulled inward when the glove is worn.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A wrist restraining glove 110 according to the present invention is disclosed in Fig.1 and Fig.2. The wrist restraining glove 110 comprises a hand receiving portion 111 for wearing on a hand H covering the five fingers, the palm and the back, a wristlet comprising a band member 113 integrally connected to a wrist end of the hand receiving portion 111, and a tension member (tension means) 115 mounted on a palmar surface of the hand receiving portion 111 and the band member 113. The hand receiving portion 111 is made of cloth, leather etc. The male and female fasteners 114a,114b so-called "hook and loop type fastener" are provided at the both ends of the band member 113. After the hand H (the fingers and the palm portion) is inserted into the hand receiving portion 111, the band portion 113 is firmly wrapped around a wrist of the hand H engaging the male fastener 114a with the female fastener 114b. The tension member 115 is provided on the palmar surface of the glove 110 extending from the wrist-end toward the knuckle-end. It is made of resilient material such as rubber, resin etc. which can produce a tensile restoring force when stretched. When it is pulled in a direction "A" shown in Fig.2, a tensile force in a direction opposite to "A" is created in the tension member 115. Therefore, when the hand is pivotally bent outward about the wrist as shown by an arrow "Y" in Fig.1, the tension member 115 is pulled in the direction of "A" and a force in an opposite direction to "A" (tensile force) is produced in the tension member 115. As a result, when the hand is pivotally bent outward (in a direction of "Y"), the force in an opposite direction to "A" is applied to the hand so as to pull back the hand inward. The further the hand is bent outward, the stronger is the opposite force to "A". When the hand is stretched straight, the force in an opposite direction to "A" is so set as to be zero or greater than zero. When the wrist restraining glove 110 is worn on the hand, the outward pivotal movement of the hand about the wrist can be suppressed by the force in an opposite direction to "A". However, the opposite force to "A" has little influence on the lateral (or sideward) pivotal movement (the cocking pivotal movement) of the hand. In other words, the pivotal movement of the hand in the direction of "X" in Fig.37A is permitted but the pivotal movement in the direction of "Y" in Fig.37B is suppressed by the wrist restraining glove 110 to assist to easily enable an accurate and powerful swing. When a golf club 1 is swung by the hand H with the wrist restrainer 110, the outward bending pivotal movement of the hand 50 as shown by the arrow "Y" in Fig.1 can be suppressed during swinging the club 1. Though the tension member 115 suppresses the outward pivotal movement of the hand H, the lateral pivotal movement of the hand H parallel to the back is almost free. As a result, when the golf club 1 is swung by the hand H with the wrist restraining glove 110, only the outward pivotal movement of the hand H is suppressed by the tension member 115 while the lateral pivotal movement (cocking movement) of the hand H is permitted to enable an accurate and powerful swing of the club 1. At the finishing stage of the swing, the hand H is easily forcibly bent outward by the inertia of the swung club 1, whereby the wrist or the hand could be hurt by being bent excessively. However, if the wrist restraining glove 110 is worn, an excessive bending pivotal movement of the wrist can be prevented by the tension member 115 and the inertia force is absorbed by the tension member 115. Further, the hand H is pulled back inward by the tensile force of the tension member 115. In the above embodiment, the glove 110 is used for golf, but the wrist restraining glove according to the present invention can be used for other sports, such as tennis, baseball, hockey, etc. In these sports, the glove helps to produce an accurate and powerful swing of a racket, a bat, a stick etc. Further, it helps to prevent an excessive bending pivotal movement of the hand at the finishing stage of the swing. The glove according to the present invention can also used for driving as shown in Fig.3. When the glove 110 is worn on driver's hands H to grasp a steering wheel S1, an unnecessary outward pivotal movement of the hands H is suppressed to relieve fatigue in the hands during driving. The glove according to the present invention can also used for a physical works, such as for digging the earth by a shovel S2 as shown in Fig.4 with hands H1 and H2 gripping the shaft and handle S2a and S2b, respectively. The glove can also used for skiing. Other embodiments of the glove according to the present invention are described below. A wrist restraining glove 120 shown in Fig.5 comprises a fingerless hand receiving portion 121, and a band member 123. Intermediate portions 123a of the band member 123 is made of rubber to make the wrist band comprising a band member 123 extensible. Male and female buttons 124a,124b is provided on the both ends of the band member 123. A tension member 125 is provided on the palmar surface of the hand receiving portion 121 and the band member 123. It is mounted on the palmar surface extending from the wrist-end toward the knuckle-end. After a hand is inserted into the hand receiving portion 121, the band member 123 is wrapped around a wrist of the hand engaging the male and female buttons 124a,124b with each other. Since the rubber portions 123a provide elasticity, the band member 123 is firmly wrapped around the wrist. The tension member 125 provides a resisting force to an outward pivotal movement of the hand about the wrist. Therefore, the outward pivotal movement of the hand during a swing of a golf club can be effectively suppressed. In the above embodiments, the tension member 115,125 can be provided so as to produce a tensile force against the outward pivotal movement of the hand only when the hand is bent outward. However, it is preferably provided so as to produce a tensile force to some extent even when the hand is being stretched straight. Another wrist restraining glove 130 according to the present invention is shown in Figs.6 to 8. The glove 130 comprises a hand receiving portion 131 made of cloth, leather,etc., a band member 133 of a wristlet integrally connected to a wrist end of the hand receiving portion 131, and a tension member 135 mounted on a palmar surface of the band member 133. The tension member 135 is made of resilient material such as rubber, resin etc. It extends from the wrist-end toward the knuckle-end. A male and a female fastener 134a,134b are provided on the two ends of the band member 133. As shown in Fig.7, the band member 133 is formed so as to be bent toward the palmar side of the hand. When the glove 130 is worn on the hand and the band member 133 is firmly wrapped around a wrist, the palmar side portion of the glove is pulled toward the wrist as shown by an arrow "Z" in Fig.8. Accordingly, the hand is pulled so as to be pivotally moved inward about the wrist in the direction shown by an arrow Y'. Since the tension member 135 has an elasticity, when the hand is outwardly bent about the wrist, a tensile force tending to pull the hand inward is produced in the tension member 135. Another glove according to the present invention can be formed as shown in Fig.9. The glove 140 comprises a hand receiving portion 141 and a band member or wristlet 143. The back surface of the hand receiving portion 141 inclines to the back surface of the band member 143 by an angle "a". Therefore, the outward pivotal movement of the hand can be effectively suppressed even if no separate tension member is provided. The tension member is constituted by palmar portions of the hand receiving portion of the glove itself. A glove 160 having a cut-out 162 on a palmar surface of the glove is shown in Fig.10. The cut-out 162 is formed laterally on the palmar surface of the bottom portion of a hand receiving portion 161 (or a portion between the hand receiving portion 161 and a band member 163). The cut-out 162 is formed as shown in Fig.11A by removing a part 161' of the hand receiving portion 161b. Then the edges of the cut-out are sewed together as shown in Fig.11B. Accordingly, the back surface of the hand receiving portion 161 inclines to the back surface of the band member 163 by an angle "a". Further, a glove 180 having a tension member 185 in a cut-out 182 can be formed as shown in Fig.12. The tension member 185 is made of a resilient material such as rubber. Therefore, the outward pivotal movement of the hand about the wrist can be suppressed though a certain amount of outward pivotal movement (shown by an arrow Y'') is permitted. A different wrist restrainer 210 is shown in Figs.13 and 14. The wrist restrainer 210 comprises a wristlet with a band member 211 having a male and a female fasteners 214a,214b so called as "hook and loop type fastener" on the both ends, a palmar member 213 having a ring portion at the tip end, and a tension member 212 integrally mounted on the palmar surfaces of the band member 211 and the palmar member 213. The band member 211 is made of slightly adhesive material to the skin such as reticulated rubber, resin or plastic, vinyl, leather, carbon fiber, glass fiber or other textiles. The palmar member 213 is made of cloth or synthetic fiber. The tension member 212 is made of resilient material such as rubber, vinyl, resin (or plastic) or other flexible textiles. The wrist restrainer 210 is worn on a hand H as shown in Fig.14. The four fingers are inserted into the ring portion of the palmar member 213, and the band member 211 is firmly wrapped around a wrist H1 engaging the fasteners 214a,214b with each other. When the tension member 212 made of resilient material is pulled as shown by an arrow "A" in Fig.13, it produces a tensile force against the pulling force "A". Therefore, when the hand is bent outward (in the direction shown by the arrow "Y") about the wrist, the tension member 212 is pulled in the direction of arrow "A" to produce the tensile force therein. The tensile force acts to bend the hand back inward. As described above, the outward pivotal movement of the hand about the wrist can be suppressed by the tensile force produced in the tension member 212. However, the lateral pivotal movement of the hand parallel to the back of the hand (the pivotal movement called as "a cocking pivotal movement" in a golf swing) is not suppressed. The band member 211 is preferably made of reticulated rubber or textile 211a' for improved ventilation of the skin (so as not to become hot and stuffy) as shown in Fig.15. It can also be made of cloth or rubber with numerous air-ventilation ventilation holes 211a'' as shown in Fig.16. A different wrist restrainer 250 is shown in Fig.17. The wrist restrainer 250 comprises a band member 251 and a glove member 252. The glove member 252 is formed so as to cover at least the palm portion of the hand. A hole for inserting a thumb is formed in the glove member 252. A cut-out 253 is formed laterally on a palmar surface of the glove member 252 (or on a palmar surface between the glove member 252 and the wristlet or band member 251). The cut-out is sewed together so as to bend the hand receiving portion 252 inward. Accordingly, when the wrist restrainer 250 is put on the hand, the outward pivotal movement of the hand can be suppressed. The wrist restrainer 250 is preferably to be made of resilient textile which is extensible longitudinally, whereby the pivotal movement of the hand can be permitted. A variation of the above wrist restrainer is shown in Fig.18. The wrist restrainer 260 shown in Fig.18 also has a cut-out 264. But, instead of sewing the cut-out in a glove member 262 closed, a tension member 264 is provided in the cut-out 264. When the hand H is bent outward as shown by an arrow Y in Fig.18, a resisting tensile force to pull back the hand inward as shown by an arrow Y' is produced by the tension member 264. Therefore, the outward pivotal movement of the hand is permitted to some extent but the hand can be pulled back inward so as not to be bent outward excessively. A different wrist restrainer 270 is shown in Fig.19. The wrist restrainer 270 comprises a band member 271, a palmar member 272 and finger ring members 273 (273a,273b). The two fingers are inserted into the finger ring members 273a,273b respectively as shown in Fig.19. The band member 217 and the palmar member 272 are preferably made of resilient material such as extensible textile. A simple wrist restrainer 280 as shown in Fig.20 can be used. The wrist restrainer 280 comprises a band member 281 and a simple palmar member 282. When a golf club is grasped by a hand H, the palmar member 282 is sandwiched between the hand H and the club. Therefore, when the hand is moved outward, the palmar member 282 is pulled to resist the outward pivotal movement of the hand. Another wrist restraining glove 360 according to the present invention is shown in Figs.21A and 21B. Fig.21A shows the palmar side of the glove 360 and Fig.21B shows the back side of the glove 360. The wrist restraining glove 360 comprises a hand receiving portion 361 made of cloth, leather etc., and a wristlet 363 integrally formed with the hand receiving portion 361. The wristlet 363 includes a wrist wrapping member 363a and a band member 363b. As shown in Figs. 32A and 32B, a lateral cut-out 367 is formed on a palmar surface 361b between the hand receiving portion 361 and the wristlet 363, and a zip fastener 366 is provided on the cut-out. The wrist wrapping member 363a includes an resilient material so as to be extensible in a direction of "B". A longitudinal cut-out 365 is formed on a back surface 361a of the wristlet 363. On the outer surface and the inner surface of the wrist wrapping member 363a, a male and a female fastener 362a,362b such as a hook and loop type fastener are provided. After a hand is inserted into the hand receiving portion 361, the fasteners 362a,362b are engaged with each other to firmly wrap the wrist by the wrapping member 363a. Further, the band member 363b is connected to the wrapping member 363a. The band member 363b can be wrapped over the wrapping member 363a, and is extensible in a direction of "C". A male and a female fasteners 364a,364b are provided on a tip end of the band portion 363b and on the wrapping portion 363a as shown in Fig.21B. The band member 363b is wrapped over the wrapping member 363a and the fasteners 364a,364b are firmly engaged with each other. As a result, the wristlet 363 is firmly wrapped around the wrist. Then, the zip fastener 366 is closed as shown in Fig.22A. When the zip fastener 366 is closed, the back surface 361a of the hand receiving portion 361 inclines inward to the back surface of the wristlet 363 by an angle "a". The angle "a" can be adjusted by changing the width of the lateral cut-out 367. When the zip fastener 366 is opened, the hand receiving portion 361 (and the hand) can be bent outward as shown in Fig.22B. Accordingly, when the zip fastener 366 is closed, the outward pivotal movement of the hand about the wrist can be effectively suppressed during a swing of a golf club. The closed zip fastener 366 restricts the outward pivotal movement of the hand but does not restrict the lateral pivotal movement (the cocking pivotal movement) of the hand to permit a smooth swing of the club. The hand receiving portion 361 and the wristlet 363 are preferably made of resilient material such as extensible textile. A variation of the wrist restraining glove is shown in Figs.23-24. The wrist restraining glove 370 comprises a hand receiving portion 371 and a wristlet 373. The wristlet 373 has the same construction as that of the glove 360 shown in Figs.21-22. A zip fastener 376a,376b is also provided on a palmar surface 371b of the hand receiving portion 371. The only difference between these gloves 360 and 370 is the lateral cut-out 367 of the glove 360. No cut-out is formed on the glove 370. When the zip fastener 376a,376b is opened, the outward pivotal movement of the hand is largely permitted as shown in Figs.23A and 23B. Namely, the outward bending angle "a1" of the hand is large. But, when the zip fastener is closed, the outward pivotal movement is restricted as shown in Figs.34A and 34B. The outward bending angle "a2" is small. Instead of the zip fastener 376a,376b, a male and female fasteners 386a,386c so-called as a hook and loop type fastener can be used to compose a wrist restraining glove 380 as shown in Figs.25-26. When the fasteners 386a,386c are disengaged, a large outward pivotal movement of the hand is permitted as shown in Fig.25B. Namely, the outward bending angle "a1" of the hand is large. But, when the fasteners are engaged with each other, the outward pivotal movement is restricted as shown in Fig.26B. Since the engaging position of the fasteners 386a,386c can be adjusted, the outward bending angle "a2" is adjustable. A different wrist restraining glove 410 according to the present invention is shown in Figs.27 and 28. Fig.27 shows a back side of the glove 410 and Fig.28 shows a palmar side. The wrist restraining glove 410 comprises a hand receiving portion 411 for receiving five fingers, a wristlet 412 integrally connected to the hand receiving portion 411. A longitudinal cut-out 416 is formed on the back side of the glove 410. The cut-out 416 is formed on the left side (near the fifth finger) so as to give a space for fasteners on the back surface of the glove 410. A wrist band member 413 is connected to the wristlet 412 at the left edge 416a of the cut-out 416. A portion (a palmar portion) of the wristlet 412 includes an extensible member 412a made of resilient material such as rubber to produce a tensile force as shown be an arrow "B" in Fig.38, when being wrapped around the wrist. When the glove is worn on a hand, the wrist band member 413 is wrapped over the wristlet 412 around a wrist H1 as shown in Figs.29A and 29B. When the wrist band member 413 is wrapped over the wristlet 412, a male and a female fastener 414a,414b are engaged with each other to keep the wrist band member 413 being wrapped firmly. A back fastening flap member 417 is connected to the hand receiving portion 411 at the left edge 416b of the cut-out 416. A male and a female fastener 418a,418b are provided on a inner surface of the back fastening flap member 417 and on the outer back surface 411a of the hand receiving portion 411. A tension member 415 is provided on the bottom palmar surface of the hand receiving portion 411. The tension member 415 is made of an resilient material and is extensible in a direction as shown by arrows "A" in Fig.28. Because of elasticity of the tension member 415, when it is pulled in a direction "A" as shown in Fig.28, it produces a resisting tensile force opposite to the force "A". When the hand is bent outward (in a direction shown by an arrow "Y" in Fig.29B), the tension member 415 produces the resisting tensile force. Accordingly, when the hand is bent outward, the tension member 415 pulls back the hand inward. Another wrist restraining glove 450 according to the present invention is shown in Figs.30 and 31. The glove 450 comprises a hand receiving portion 451 and a wrist potion 452. A longitudinal cut-out 456 is formed on a back surface of the glove 450. The cut-out 456 is formed on the left side (near the fifth finger) so as to give a space for a back restraining flap member 459 on the back surface of the glove 450. The back restraining flap member 459 which can cover the back surface of the hand receiving portion 451 and the wristlet 452 is connected to the left edge 456a of the cut-out 456. A male and a female fastener 458a and 458b which can be engaged with each other are provided on the inner surface of the back restraining flap member 459 and on the outer back surface of the glove 450. The fasteners 458a and 458b may comprise so-called hook and loop type fasteners. The back restraining flap member 459 comprises an inner plane member 459a on which the fastener 458b is attached, and an outer plane member 459b. The peripheries of the inner and outer plane members 459a,459b are sewed together to form an envelope-shape inner space or pocket between the plane members 459a,459b. A restraining plate 459c made of resilient material such as rubber is loosely placed in the inner space which is formed between the plane members 459a,459b. Though not being illustrated in Figs.30 and 31, a tension member is provided on the palmar surface of the glove 450 which is similar to that shown in Figs.1 and 2. When the glove 450 is worn on a hand, the back restraining flap member 459 is folded on the back surface of the glove 450 to engage the male and female fasteners 458a,458b with each other. Therefore, a wrist is firmly wrapped by the wristlet 452. The outward pivotal movement of the hand about the wrist is effectively suppressed by not only the tension member on the palmar surface but also the restraining flap member 459. Since the restraining plate 459c is loosely placed in the inner space between the plane members 459a,459b, the lateral pivotal movement of the hand is not restricted. A modified wrist restraining glove 450' according to the present invention is shown in Fig.32. The glove 450' has a similar construction to the glove 450 of Figs.30,31. The only difference is the notches 459d' and 459e' which are formed on a back restraining flap member 459' and a fastener 458a'. Because of the notches 459d' and 459e', the lateral pivotal movement of the hand around the wrist is easier. A further modified wrist restraining glove 550 according to the present invention is shown in Figs.33 and 34. The glove 550 also has a similar construction to the glove 450 of Figs.31,32. The only difference is in the construction of a back restraining flap member 559 of the wrist restraining glove 550. The back restraining flap member 559 comprises a flap member 559 and a resilient resisting plate 555. A male and female fastener 558 such as a loop and hook type fastener are provided on the back surface 551a of a hand receiving portion 551 and the inner surface of the flap member 559. The resilient resisting plate 555 made of elastic material such as rubber, resin etc. is integrally mounted on the outer surface of the flap member 559. The resisting plate 555 has a gourd-shape configuration with a middle narrow portion 555b. A knuckle-end portion 555a and a wrist-end wide portion 555c are wider than the middle portion 555b. However, the middle portion 555b is thicker than the knuckle-end portion 555a and the wrist-end portion 555c. Accordingly, the middle portion 555b has a large rigidity against being bent outward but has a small rigidity against being bent laterally. When the hand on which the glove 550 is worn is bent, the middle narrow portion 555b is mainly bent. Therefore, the hand is easily bent laterally but is difficult to bend outward. A further embodiment of a wrist restraining glove 460 according to the present invention is shown in Fig.35. The glove 460 comprises a hand receiving portion 461 and a wristlet 462. A band member 463 which has a male and a female fastener 464a,464b at the both ends is included in the wristlet 462. A restraining plate 465 made of resilient material such as rubber, resin etc. is attached on the bottom palmar surface of the glove 460 as shown in Fig.35. The restraining plate 465 works by suppressing the outward pivotal movement of the hand as shown in Fig.36B. If the restraining plate 465 is not included in the glove 460, the outward pivotal movement of the hand is permitted almost freely as shown in Fig.36A. However, the restraining plate 465 resists the outward pivotal movement of the hand by pulling the palmar portion of the glove as shown in Fig.36B when the hand is bent outward. The restraining plate 465 has a cut-off portion 465a as shown in Fig.35. Because of the cut-off portion 465a, the restraining plate does not interfere with a grip end of a golf club when the golf club is grasped by a hand.
